Boardies,
Arrival at MoBay was a bit different! They have these machines - You go over, they take your picture and you present the slip of paper to an attendant as you go in.. Not sure what the purpose of it all was!! Then on the way back - no custom forms needed! When you arrive state side, again you go to a machine - put your passport in, answer some questions - the machine takes your picture and gives you a slip that you present to an Immigration officer as you leave.. A bit different than a year ago!
